Page_Load

Vi
Is there a way to determine in Page_Load as a result of what action (what
button click) the form was submitted?

Thank you

With autopostback property set to true, there will be two hidden variable in
your form __EVENTTARGET and __EVENTARGUMENT which you can access in
Page_Load event to get the control name which caused the postback.
__EVENTTARGET will have the object which fired the post back event.

AFAIK no

this is a bit of a pain sometimes. you may need to delay doing some
processing until the prerender event.

In one form, I just had all the event handlers set an instance variable
called WhichButtonWasClicked. Then I did all the work in PreRender

Both __EVENTTARGET and __EVENTARGUMENT return null.
I read on the web that some controls reset the value of these hidden fields.
Is there a way to overcome this problem or other ways to determine the
control that submitted the form?

Thanks.
